宋人方书其最着者，陈氏《三因方》，许氏《本事方》之类，我邦既刻之行于世久矣。
而至王氏《百一选方》才传抄本，世罕觏者。医官千田子敬特好阅之，试诸刀圭，奇特尤多，
然
书同布于世焉。会西京荻子元（元凯）应召来斯都，相见于医学中，语次及此书，子元便贷
以其所藏元人镂板完好者，因改取此为蓝本，更加详校，子敬于是无复遗憾焉。迨其迄功，
丐予作序，予考历代医传无传王氏者，惟宋陈振孙《书录解题》载∶《是斋百一选方》，三十
卷，山阴王 孟玉撰，百一言其选之精也。又宋陈造《江湖长翁集》有百一方题言，称王氏
名，字孟玉，是斋其号，山阴人，绍熙中仕为汉阳史，斯书裒集十九年始成。又天台章楫
序称，是斋，王史君 ，守古沔阳，公余裒集始就，盖其人非医，效陆忠宣忠州之录者。《古
今医统》作字孟欲，误矣。又清朱彝尊《曝书亭集》有此书跋，谓《书录解题》云三十卷，
宋《艺文志》作二十八卷，其所藏元本仅二十卷，因疑经后人选择者。今此本亦二十卷，即
与朱所言符矣。而其分门三十一，录方一千有余，条列井井甚备，则未可遽据《解题》及《宋
志》所载卷数，而斥为非王氏原帙也。子敬已研精方术，最爱是册，而子元从千里外来，以
KT其举者，实非偶然也。近者同僚山本宗英（惟直）刻《杨氏家藏方》，吉田快庵（赖干）
刻《仁斋直指》，津轻意伯（健寿）刻《外科精要》，桂川甫周（国瑞）活字嵌印，以行数种，
其他诸医官家锓方书，陆续告竣，盖医学之盛，未曾有如今日者，乃是国家深仁之所施及，
于戏！不亦韪乎哉！因并书之。
宽政十一年岁在己未端午日

宋代医方书籍中最为著名的，有陈氏的《三因方》、许氏的《本事方》等，我国（日本）早已刻印并在世间流传。
然而到了王氏的《百一选方》，却仅有传抄本，世间很少见到。
医官千田子敬特别喜好阅读此书，尝试用于临床治疗（刀圭：古代量取药粉的器具，代指医疗实践），发现疗效奇特之处非常多，
但是这本书未能广泛布行于世。
恰逢西京荻子元（字元凯）应召来到京都，在医学界相见，交谈中谈及此书，荻子元便借出他所收藏的元代雕版印刷完好无损的本子，
因此决定以此作为蓝本进行修订，并加以详细校对，千田子敬于是再无遗憾了。
等到工作完成，千田子敬请求我为其作序，我考察历代医学传记中没有关于王氏的记载，只有宋代陈振孙的《书录解题》中记载：《是斋百一选方》，三十卷，由山阴人王孟玉撰写，“百一”意指所选方剂精当（意为百中无一失）。
又据宋代陈造的《江湖长翁集》中有为百一方写的题言，称王氏名孟玉，字孟玉，“是斋”是他的号，他是山阴人，绍熙年间担任汉阳史职，这部书汇集整理十九年才最终完成。
另外天台章楫的序言称，“是斋”这位王史君，曾治理古沔阳，在公务之余汇集整理才得以成书，大概这个人并非医生，而是效仿陆忠宣在忠州时的做法。
《古今医统》中写作“字孟欲”，是错误的。
又据清代朱彝尊的《曝书亭集》中有此书的跋文，说《书录解题》记载为三十卷，宋代《艺文志》记载为二十八卷，他所藏的元朝版本仅二十卷，因此怀疑是经过后人筛选删减过的。
如今这个版本也是二十卷，正与朱彝尊所说的相符。
而且该书分为三十一门，收录方剂一千多首，条理清晰详尽完备，那么就不能立刻依据《解题》及《宋志》所载的卷数，而斥责它不是王氏的原著。
千田子敬已经深入研究方术，最爱这一册，而荻子元从千里之外赶来，以协助他刊刻此书，这实在不是偶然。
近来同僚山本宗英（字惟直）刻印了《杨氏家藏方》，吉田快庵（名赖干）刻印了《仁斋直指》，津轻意伯（名健寿）刻印了《外科精要》，桂川甫周（名国瑞）采用活字嵌印技术，刊行了几种，
其他各位医官家中刻印医方书籍，也陆续宣告完工，可以说医学的兴盛，从未有过像今天这样的盛况，这大概是国家深厚仁爱所施及的结果，
啊！不也是正确的吗！因此一并记下。
宽政十一年岁次己未端午节
丹波元简廉夫撰
Among the medical formularies of the Song Dynasty, the most renowned include Chen's *San Yin Fang* (Three Causes Formulary) and Xu's *Ben Shi Fang* (Formulas from Actual Experience), which have long been printed and circulated in our country [Japan].
However, Wang's *Bai Yi Xuan Fang* (Selected Hundred-and-One Prescriptions) existed only in manuscript copies and was rarely seen in the world.
Physician Qian Tian Zijing had a particular fondness for reading this book; when applied to clinical practice [dao gui: an ancient measuring spoon for powder, metaphorically referring to medical treatment], he found its therapeutic effects to be particularly remarkable.
Yet, the book had not been widely disseminated.
Coincidentally, Di Ziyuan (courtesy name Yuan Kai) from the Western Capital was summoned to the capital city, where they met within the medical community. During their conversation regarding this book, Ziyuan lent his well-preserved Yuan Dynasty woodblock-printed copy.
Consequently, it was adopted as the blueprint for revision and underwent detailed collation, leaving Qian Zijing with no regrets.
Upon completion, Qian Zijing requested me to write a preface. I examined historical medical biographies but found no records of Wang; only Chen Zhen Sun's *Shu Lu Jie Ti* (Record of Books with Explanatory Notes) from the Song Dynasty mentions: *Shi Zhai Bai Yi Xuan Fang*, 30 volumes, authored by Wang Mengyu of Shanyin. "Bai Yi" implies the precision of the selected prescriptions [meaning one out of a hundred is flawless].
Furthermore, Chen Zao's *Jiang Hu Chang Weng Ji* (Collection of the Old Man of Jianghu) contains a preface for the hundred-one formulas, stating that Wang's given name was Mengyu, courtesy name Mengyu, and his pseudonym was "Shi Zhai." He was from Shanyin and served as the Historian of Hanyang during the Shaoxi era. This work took nineteen years of compilation to complete.
Additionally, Zhang Ji's preface from Tiantai states that "Shi Zhai," Lord Wang Shijun, governed ancient Mianyang and compiled the work during his spare time from official duties. It seems he was not a physician but rather emulated Lu Zhongxuan's practices in Zhongzhou.
*Gu Jin Yi Tong* (Comprehensive Medical History) erroneously lists his courtesy name as "Meng Yu."
Moreover, Zhu Yizun's *Pu Shu Ting Ji* (Collection from the Sun-Drying Pavilion) from the Qing Dynasty includes a postscript noting that while *Shu Lu Jie Ti* records 30 volumes and the Song *Yi Wen Zhi* (Art and Literature Catalog) records 28 volumes, the Yuan edition he possessed contained only 20 volumes, leading him to suspect it was a selection edited by later generations.
This current edition also comprises 20 volumes, aligning with Zhu's account.
The book is divided into 31 categories, recording over 1,000 prescriptions, organized clearly and comprehensively. Therefore, one cannot immediately dismiss it as non-original to Wang based solely on the volume counts cited in *Jie Ti* and the *Song Zhi*.
Zijing has meticulously studied formula arts and cherishes this volume greatly. Ziyuan traveled from a thousand miles away to assist in its publication, which is certainly not coincidental.
Recently, colleagues Shanben Zongying (courtesy name Weizhi) printed *Yang Shi Jia Cang Fang* (Yang Family's Household Formulary); Jiyada Kainan (name Lai Gan) printed *Ren Zhai Zhi Zhi* (Direct Guidance from Ren Zhai); Tsugaru Iboku (name Kenshu) printed *Wai Ke Jing Yao* (Essentials of Surgery); and Katsukawa Foshu (name Guorui) utilized movable type printing for several editions.
Other physicians' families have also successively completed the carving and printing of their medical formularies. The prosperity of medicine has never been as great as it is today, which is undoubtedly a result of the profound benevolence bestowed by the state.
Ah! Is this not praiseworthy? I record this together.
